  4. 2. The GLAST Satellite Calorimeter

    Author : Georg Johansson; Avdelningen för Biomedicinsk teknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; GLAST; CsI Tl crystals; electromagnetic calorimeter; hodoscopic assembly; satellite-born detector; Dark Matter; cosmic gamma radiation;

    Abstract : The Gamma Ray Large Area Space Telescope (GLAST) is a multi-national satellite mission with aim to study the high-energy gamma ray sky. The main instrument is the Large Area Telescope (LAT) that consists of 16 towers, each housing a silicon strip precision tracker and a CsI(Tl) calorimeter. READ MORE

  5. 3. Satellite measurements and climate modelling of water in the tropical upper troposphere

    Author : Marston Sheldon Johnston; Chalmers University of Technology; []
    Keywords : Model; Satellite; Climate; Humidity; Radiation; Tropics;

    Abstract : The International Panel on Climate Change (2007) has identified key areas of uncertainty with regards to future climate change, e.g., the upper troposphere. A portion of the uncertain- ties come from climate models and this makes model accuracy very important. READ MORE

  6. 4. Satellite Limb-Scatter Observations of Stratospheric NO2 and O3 -Retrievals, Validation and Applications

    Author : Samuel Brohede; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES; satellite; NO2; Odin; limb-scatter; validation; OSIRIS; stratosphere; remote sensing; O3; retrieval;

    Abstract : Global observations of vertically resolved atmospheric constituents with high temporal and spatial sampling are crucial for various scientific assessments of ozone depletion and climate change. This thesis explains how such data can be retrieved from satellite limb-scatter observations. READ MORE

  7. 5. Mobile Satellite Broadcast and Multichannel Communications : analysis and design

    Author : Cristoff Martin; Björn Ottersten; Jack Winters; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; communications; satellite broadcast; mobile; MIMO; asymptotic analysis; spatial multiplexing; Signalbehandling; Signal processing; Signalbehandling;

    Abstract : In this thesis, analytical analysis and design techniques for wireless communications with diversity are studied. The impact of impairments such as correlated fading is analyzed using statistical models. Countermeasures designed to overcome, or even exploit, such effects are proposed and examined. READ MORE
